The sky was cloudy and dark and by the look of it, it is going to rain soon.. good thing that you're already inside the bus and as you notice the same guy again you always get to see him everytime you ride the bus.

Namjoon sats the back of the bus since it's full and the available seat is only at the back, he hates to sit in here since he can't see the outside clearly and he can't lean his head well on the window, he looks around the bus with a sigh and he as well saw you.
